Network & Host Analysis: Network Observations

“Knowing what goes on over a network requires a high-level picture of it. The ability to conceptualize your network s structure capabilities and events is essential to protecting it. In this course you ll explore the concepts and tools required to identify and visualize your network components.
You ll work mostly with the open source network protocol analyzer Wireshark. You ll start by displaying protocol hierarchies and identifying network endpoints. You ll then describe considerations for visualizing networks and create a network diagram using Visio.
Next you ll outline network security assessment methods recognize the use of baselines for network management and carry out baseline activity monitoring. You ll also look at ways of capturing network data. Lastly you ll explore how Wireshark combines with other tools such as Nmap SSH and firewalls.”
